Be it known that I, Wnz'ro v FifDArmomf a citizen of..th e.tUnited States, :,rs;iding: at

Sutter Creek, in the county of A'inador and State of California, have invented certain new and useful Improvements in Movable Sprays for Mineral-Washing ;'fand I do hereby declare the following-tobe a clear, full,

and exact descriptionfof the same, such as will enable others skilled in the art to which itappertains'to make and'use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application. 1 p

This invention relates to improvements in paraphernalia used in connection with the concentration of crushed ore slimes, the ob- "ject of the invention being to produce a spraying means for washing off .and collecting the valuable mineral concentrates.

The device is particularly designed for use with a plurality of trays arranged in of the trays with water and in such amanner as to remove the accumulated mineral as fast as the rotation of the concentrating trays past the spraying zone. i

A. further. object jof the invention is to i produce a simple and inexpensive device and yet one which will be exceedingly effective "for the purposes forwhich it isjdesigned.

These objects, I accomplish by-means of such structure and relative arrangement of the parts as will fullyfappearb'y aperusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the i several views.

My improved spraying meansembodies a carriage consisting of a pair of spaced pulleys 7 adapted toroll back and forth on the tracks 5. and a similar carriage 8 adapted :to moveback and forthv on the tracks 6,

which carriages form the supporting means for a vertical spray pipe 9 adapted to receive water from any suitable source and provided with a plurality of individual spray pipes 10, one for each of the trays or tables 1, each pipe 10 having a plurality of spraynozzles 11. i

Flexibly connected with the pipe 9, as

at 12, are a pair of connecting rods 13 adapted to connect with the crank arms 14 of a the entire surface of said trays from end to able mineral deposits thereon. From. the foregoing description it will readily beseen that I have produced such of the invention as set forth herein.

While this specification sets forth in detail the device, still in 'pr'actice,jsuch deviations from such detail may be resorted to as do not form a departure from the spirit of the invention. Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is l 1.
